Please note:
Entries in the above species list are the original binomina of species according to Carlgren's 1949 catalog. Nomenclatorial inconsistencies need to be resolved in a future revision of this genus (see below).

Characteristics

Actiniidae with very wide pedal disc and smooth, rather low column. A ring of simple or slightly
compound marginal spherules in the deep fosse. These are commonly conspicuous but can be
covered up by the margin in contraction. Sphincter weaker or stronger, diffuse, rarely with a slight
tendency to be meso-ectodermal. Tentacles retractile of ordinary length, their longitudinal muscles
ectodermal. Perfect mesenteries numerous. All stronger mesenteries, save the directives, fertile.
More mesenteries at the base than at the margin. Retractors of the mesenteries diffuse. Cnidom:
spirocysts, atrichs, basitrichs, microbasic p-mastigophors.

About This Page

Please note that Carlgren's text contains a number of errors, and much of the information is now out of date. An update of the catalog is currently under preparation in Daphne Fautin's laboratory, and the results of this work will be incorporated in future versions of this page.

Keyboarding of Carlgren's catalog was done as part of a project to create an electronic database of the sea anemones of the world, funded by NSF Grant DEB9521819, awarded to Daphne G. Fautin. This grant is in the program Partnerships to Enhance Expertise in Taxonomy
(PEET). Susanne Hauswaldt, Katherine Pearson, and April Wakefield-Pagels contributed to the keyboarding effort.

Each ToL branch page provides a synopsis of the characteristics of
a group of organisms representing a branch of the Tree of Life. The
major distinction between a branch and a leaf of
the Tree of Life is that each branch can be further subdivided into
descendent branches, that is, subgroups representing distinct genetic
lineages.
